COKE-OVEN.

' r' i I Specification of Letters Patent. Patented NOV. 14, 1911.

Application filed April 26, 1911. Serial No. 628,388.'

Toall whom it may concemf Be it known that I, ARTHUR OWEN J ONES,

a subject of the King of Great Britain, re-

siding at Whitley Bay, in the county of Northumberland England, haveinvented certain new and useful Improvements in Coke-Ovens, and of.which the following is a specification.

Coke ovens in which the coal is fed in at an open top and in which thecoked product is discharged through the base, are already known and arecommonly termed vertical coke ovens. Now the present invention refers tocoke ovens of this type, and in such ovens it has'already been proposedto provide horizontal superposed heating flues independent one of theother and all discharging the products of combustion into a commonvertical out-let flue in the structure adjacent to the front wall of theoven, while the inlet end of each horizontal flue has extended to theface of the structure andhas been there supplied with gas and air, and Ihave before proposed to supply the air to such horizontal flues bya-common air sup ply passage. horizontal flues, they have, been causedto pass within and along one side wall of an oven, around the end of theoven and have returned along and within the other side wall of the ovento the common vertical outletflue at the front end of the oven.

Now the object of the present invention is to construct the horizontalheating flues of such ovens entirely in the side walls thereof, so thatthey do not pass around the ends of the ovens, and thereby the cokingaction takes place entirely from the sides of theoven and not from theends thereof. According to this invention therefore I locate the commonvertical outlet flue or flues for each oven not immediately at the endsof the said ovens but between two adjacent ovens. One end ofeach'horizontal flue extends as heretofore to the face of the structurewhere it communicates with a vertical air flue common to all thehorizontal flues, and where also it is supplied with gas. The flue, fromits gas admittance end, extends in one side wall adjacent to one oven,and then passes by a cross passage and returns in the same sidewalladjacent to the next oven, and at its return end it communicates with avertical outlet flue (common to all the. horizontal flues) which isconstructed in the same side Wall. The horizontal flues may In theconstruction of such be arranged in such a manner that the gas 1sadmitted to that horizontal arm of one of the flues extending in thewall adjacent to the oven on one slde, while in the next horizontal fluethe gas is admitted to that horizontal arm of that flue which is in proximity to the next oven, and soon, considering a series of saidsuperposed heating flues,

and by arranging thus, the horizontal arm of one flue, into which the asis admitted directly, alternates with the orizontal arms of the fluesthrough which the products of combustion pass to the common exit. Or

the flues may be arranged in the wall between two ovens, so that thehorizontal arm into which the gas is admitted is in the cate by avertical passage with a lower flue which is vertically beneath the saidadmittance flue, and through this lower flue the products of combustionreturn. By this arrangement the requisite quantity of heat is suppliedto the charge near the base and at the thickest part thereof, and by thereturn or outlet arm being located immediately below that inlet armwhich is level with or justabove the top of the sole plate, the heat isconserved in the said inlet arm.

In order that the invention may be more readily understood, reference ismade to the accompanying drawings whereon Figure 1 is a verticaltransverse section on the line A B of Fig. 2, and Fig. 2 is a horizontalsection on the line C D of Fig. 1, showing ovens provided with fluesaccording to this invention, the left hand portion of the figure'showingthe arm of the flue connected with the gas supply (hereafter referred toas the inlet arm) and the arm of the flue connected with the main exitflue (hereafter referred to as the outlet arm) arranged in the samehorizontal planes, the right hand portion of the figures showing theinlet and outlet arms arranged in a vertical plane, two series of suchflues being arranged in one dividingor oven side wall and adapted eachseries to heat one side of one oven or coking chamber. Fig. 3 is avertical longitudinal sect1on through the flues shown at the right ofFig. 1, the section tending from the forward and rearward faces of theoven structure to the center of the dividing or side walls. Fig. 5 is avertical longitudinal section of a modified arrangement of flues shownin Fig. 3, in which. the flues extend from the forward and rearwardfaces of the oven structure to the center of the dividing or side wallbetween two ovens. Fig. 6 is avertical transverse section showing anarrangement of flues similar to that shown at the right of Fig. 1 but inwhich one series of flues arranged in a vertical plane is employed toheat the adjacent sides of two ovens, and Fig. 7 is a diagram toillustrate the effect of heating and coking chambers by means of sideflues only and Fig. 8 is a diagram illustrating the effect in knownovens where the. flues also extend around the ends of the ovens.

' In the accompanying drawings the oven structures comprise cokingchambers 1 having gas outlets 1 (see Figs. 1 and 6), front and rearwalls 2 and 3 respectively, and side or dividing walls 4. Formed in thefront wall 2 of the structure and immediately at the-end ofthe dividingwalls 4 as shown in Fig. 2, is a common vertical outlet flue 5, and acommon vertical air inletflue 6, with which latter flue communicates, bymeans of a passage 7 controlled'by a valve 8, each inlet arm. 9of theheating flues. The arms 9, according to the construction shown at theleft of Figs. 1 and 2, proceed rearwardly along the side of one cokingchamber to the end of the said coking chambers 1, and are each connectedby a cross passage 10 formed in the dividingwalls l with the outlet arm9, which extends along the opposite side of an adjacent coking chamber,and in turn communicates at its forward end with the outlet flue 5 bymeans of a passage 11 controlled by a valve 12.

The inlet arm 9 of each heating flue is fitted at its forward end with agas burner 13, and is connected as aforesaid with the air inlet flue 6,the forward end of each outlet arm being connected with the outlet flue5, and the. connection of the said outlet and inlet arms with theirrespective flues is such that considering one side of the cokingchamber, the inlet arms 9 of the flues alternate in vertical series withthe outlet arms 9 of the next upper or lower adjacent flue. Thisarrangement of flues is clearly shown at the left of Fig. 1. As shown atthe right of Figs. 1 and 2 and at Fig. 3, the heating flues instead ofextending along one sid e of a coking chamber-and returning along theside of the adjacent coking chamber as in the construction shown at theleft-of Fig. 1, are arranged so that each side .of each coking chamberis heated by an independent series of heating flues, and according tothis arrangement the inlet arm 9 of the heating flue is arrangedimmediately above or below, as the case may be, the outlet arm 9? of itsflue, thesaid arms being connected at their rearward ends by a shortvertical passage 10 in the side or dividing walls 4.

A single series of heating flues such as lastly described may beemployed to heat the adjacent sides of two adjacent coking chambers, asillustrated in Fig. 6, in which case the thickness of the dividing wallbetween the coking chambers 1 is materially decreased.

4 Obviously, the heating flues may extend from the front wall to aboutthe center of the structure and also another series extends from therearward wall to about the center of the structure, so that with one setof flues the inlet arms will open on the front of the structure whilethe outlet arms will commuarms communicating with a common ver-."

tical outlet flue in'the rearward wall of the structure, a centralpartition in the dividing side wall of an oven separating these twoforward and rearward sets of flues. Such a construct-ion is illustratedat Fig. 4: in sectional plan with these two sets of forward and rearwardflues respectively constructed on similar lines to those shown on theleft hand side. of Fig. 2, the two adjacent passages 10 in a side wallbeing divided the one from the other by the partition 14, and the otherfeatures of this construction are marked with letters corresponding tothe left hand side of Fig. 2 and will therefore be readily understood.

At Fig. 5 in vertical section is shown an arrangement of the flues invertical series similar to that illustrated and already described at theright handside of Fig. 2, there being at Fig. 5 two sets of these fluesopening on to the rearward and forward walls of the ovenstructuredivided by a partition 14. 1

At the base of the oven as shown at Fig. 1 I arrange the lowermostheating flue so that its inlet arm 15 is level with or just above thetop of the sole plate, while its outlet arm 16 is beneath it so that thecommunicating passage between the inlet arm the central plane.

I would therefore explain that it is unnecessary that the flues shoulddo so, because shown at Fig. 8) (which it does not in the.
